Symmetry constraints are a way of enforcing symmetry between the sub-cells of a double height cell. Identical blocks of logic from the netlist are paired together. The elements of each pair are placed with the same orientation in the same column in separate sub-cells. The paired blocks of logic are then treated as a group (i.e. one combined entity) when determining their position relative to other blocks of logic from the netlist.
